Abstract: A first decoder performs decoding on each data set in a first plurality of data sets using a first code; each data set in the first plurality is stored on a different chip. It is determined if the first decoding is successful; if not, a second decoder performs a second decoding on each data set in a second plurality of data sets using a second code; each data set in the second plurality includes at least some data, after the first decoding using the first code, from each data set in the first plurality. The first decoder performs a third decoding on each data set in the first plurality using the first code, where each data set in the first plurality includes at least some data, after the second decoding using the second code, from each data set in the second plurality.

Reduced complexity iterative decoding of low-density parity check codes based on belief propagation
TL;DR: Two simplified versions of the belief propagation algorithm for fast iterative decoding of low-density parity check codes on the additive white Gaussian noise channel are proposed, which greatly simplifies the decoding complexity of belief propagation.
EVENODD: an efficient scheme for tolerating double disk failures in RAID architectures
TL;DR: A novel method for tolerating up to two disk failures in RAID architectures based on Reed-Solomon error-correcting codes, which can be used in any system requiring large symbols and relatively short codes, for instance, in multitrack magnetic recording.
